Pluto is no longer a Planet. Or is it...

Is Pluto a planet?


In the year 1930, an American Astronomer discovered Pluto. It got its name from an 11 year-old British Girl, who suggested Pluto as the name after the Greek God of The Underworld. She loved Greek Gods and Goddesses.So in August 24th, 2006, there was a debate whether or not Pluto should be a planet or downgraded to a Dwarf Planet. So is it a Dwarf Planet or still better as a Planet?

Yes, it is a dwarf planet.

It is believed that Pluto is a dwarf planet because IAU (Intergalactic Astronomy Union) set a list of qualifications a planet must have to be officially a planet. These rules are:

  • Must be in Orbit around the Sun.
  • Must have "cleared it's neighborhood
  • Must not be a satellite (orbit anything other than The Sun
  • Nearly be round in Shape or atleast Spherical.
However, Pluto is in an Asteroid Field so hasn't cleared it's neighborhood. It is also in Neptune's Orbit, so its possibly a satellite or a moon of Neptune's. As well as this, it is too harsh to be a planet, some say. It is also smaller than the last official planet Mercury, most moons like Titan and it's own moon. Many also say because it's in an Asteroid Field, it may just be a very large Asteroid. It also may just be a lump of cold Asteroids bumped together, like the moon was formed. It could also be a star. As well as this, it meets all the qualifications of being a dwarf planet any many consider it too dark and wet

No, It's not a dwarf planet.

I personally agree with this. How could it be a planet so long and now not be? Will there be too many planets? What rubbish! Many argue that it is, and always be a planet. Some say because it's in an Asteroid Field is a weak excuse. If Earth and Pluto swapped positions, would Earth no longer be a Planet because it overlapped Neptune's orbit and was in an Asteroid Field? No, that's ironic. Also, why categorize some of the Solar System's planets as dwarfs all of a sudden? Thats like saying a shade of red is too light to be red and is green. Furthermore, Eris was a dwarf planet discovered in 2005. It's the largest of the five dwarf planets, and many consider it a Planet. What difference is Pluto, Make Make and the other dwarf Planets?

To summarize... 

Sadly, Pluto will officially remain a dwarf planet. Yet there will probably be a debate for decades, until it is clear. In a couple of decades time this will probably be clear, but until then, there are 8 official planets, however some still believe there is 9. Nobody can disprove or prove it. What do you think?
